Zheng Caiguo is one of the authors included in this Chinese book database. Public information about him is limited: details such as his birthplace, education, and professional positions are not recorded. Two of his works are currently available in the database: Engineering Drawing (2nd Edition) and an accompanying Engineering Drawing Exercise Book, both within the field of engineering drawing instruction. Judging from the titles and classifications, his writing centers on industrial technology and exam preparation, emphasizing basic drafting standards, drawing representation, and practice exercises. The textbook and exercise book are designed to be used together, allowing readers to learn while practicing. Such works typically serve engineering students at higher education institutions and candidates preparing for related professional qualification exams, and are clearly intended as teaching aids. Owing to limited source material, a full assessment of his writing style and academic influence is difficult; readers may gain a better understanding through the specific contents of the two books mentioned above.
